Olivers Didgeridoo

Oliver Hoot had just bought a didgeridoo. However, the sound seemed a bit muffled, and although the thing would didger it just wouldn't do. Back at the shop he bought it from, the shopkeeper discovered the problem: a cuckoo was lodging in the pipe. So he blew down one end to drive it out. 

Now the three distances, of the cuckoo from each of the two ends and the pipe length, were all non-prime whole numbers (inches). Also the cuckoo would have taken the same time to fly to one end with the wind speed added to his natural speed as it would have taken to fly to the other end with the wind speed subtracted. It turned out that the cuckoo's natural speed divided by the wind speed was a square number less than 100, numerically equal to the pipe length. How long was Oliver's didgeridoo?

Hot EuroCup in Eilat

by Natalia Pogonina for her
Chess.com Tuesday column


The European Chess Club Cup is usually held in one of the European countries. This year was an exception it took place on the joint between Asia and Africa. The leading (and not only) clubs fared to Eilat, Israel, to determine the best of the best. Due to the venue choice (long travel; rather expensive city) there were fewer teams at the event than last year. In the womens section there were just 8 clubs, while in the open section 34 teams showed up. The line-up was incredibly strong: 31 players were rated 2700 and above! In case you are interested in the big names, here is a more detailed preview.


My adventures started in Moscow. For well-known reasons Israel is religious about security, so before taking a flight from the Russian capital to Tel Aviv I had to attend an interview with an Israeli security officer. He was rather surprised to hear that I am a professional chess player and started asking me all sort of questions like who is the best chess player in Israel?; who is #1 in Russia?; who is the best player in the world?. The matter was resolved after they decided to do a web search on me. The checkout was even stricter on the way from Tel Aviv to Eilat. They examined every little item in my baggage, including coins. My friend and teammate, ex-Womens World Chess Champion Antoaneta Stefanova, had spent half an hour there. This was the only drawback of the trip. Otherwise, everything was fine.
